Encoding, decoding, signing and verification (Detached JWS)
Signing and verifying is done through the Sign
and Verify
traits.
Example with writer:
use openssl::pkey::PKey;
use openssl::rsa::Rsa;
use openssl::{hash::MessageDigest};
use openssl::{
rsa::Padding,
sign::{Signer, Verifier},
};
use serde_json::{json, Map, Value};
use std::io::{Write};
use detached_jws::{SerializeJwsWriter, DeserializeJwsWriter};
let keypair = PKey::from_rsa(Rsa::generate(2048).unwrap()).unwrap();
let mut signer = Signer::new(MessageDigest::sha256(), &keypair).unwrap();
signer.set_rsa_padding(Padding::PKCS1_PSS).unwrap();
let mut header = Map::new();
header.insert("custom".to_owned(), json!("custom_value"));
let mut writer = SerializeJwsWriter::new(Vec::new(),
"PS256".to_owned(),
header,
signer).unwrap();
writer.write_all(&[0, 1, 2, 3]);
writer.write_all(&[4, 5, 6]);
let jws = writer.finish().unwrap();
let mut verifier = Verifier::new(MessageDigest::sha256(), &keypair).unwrap();
verifier.set_rsa_padding(Padding::PKCS1_PSS).unwrap();
let mut writer = DeserializeJwsWriter::new(&jws,
|h| Some(verifier)
).unwrap();
writer.write_all(&[0, 1, 2, 3]);
writer.write_all(&[4, 5, 6]);
let verified_headers = writer.finish().unwrap();
assert_eq!(
verified_headers.get("custom").unwrap().as_str().unwrap(),
"custom_value"
);
Simple example:
use openssl::pkey::PKey;
use openssl::rsa::Rsa;
use openssl::{hash::MessageDigest};
use openssl::{
rsa::Padding,
sign::{Signer, Verifier},
};
use serde_json::{json, Map, Value};
let keypair = PKey::from_rsa(Rsa::generate(2048).unwrap()).unwrap();
let mut signer = Signer::new(MessageDigest::sha256(), &keypair).unwrap();
signer.set_rsa_padding(Padding::PKCS1_PSS).unwrap();
let mut header = Map::new();
header.insert("custom".to_owned(), json!("custom_value"));
let payload = vec![0, 1, 2, 3, 4, 5, 6];
let jws = detached_jws::serialize(
"PS256".to_owned(),
header,
&mut payload.as_slice(),
signer,
)
.unwrap();
let mut verifier = Verifier::new(MessageDigest::sha256(), &keypair).unwrap();
verifier.set_rsa_padding(Padding::PKCS1_PSS).unwrap();
let verified_headers =
detached_jws::deserialize(&jws, &mut payload.as_slice(), verifier).unwrap();
assert_eq!(
verified_headers.get("custom").unwrap().as_str().unwrap(),
"custom_value"
);
